Backpack Blower
Echo PB-770
2-Stroke
The Echo PB-770 is a 63.3cc <!-- verify: echo-usa.com --> 2-stroke backpack blower and the top model in Echo's commercial PB lineup, delivering maximum air volume and velocity for the most demanding large-area clearing operations. It runs a Zama carburetor and features Echo's professional harness with lumbar support for extended-shift wear. Under daily commercial production use, monthly fuel system inspection, air filter service after each shift in high-debris environments, and harness structural inspection are routine. Built for crews managing large parks, sports facilities, and commercial campuses where throughput and air velocity are primary concerns.
